Here, the `shutdown` event handler function will write a text line `"Application shutdown"` to a file `log.txt`.

/// info

In the `open()` function, the `mode="a"` means "append", so, the line will be added after whatever is on that file, without overwriting the previous contents.

///

/// tip

Notice that in this case we are using a standard Python `open()` function that interacts with a file.

#### Adding 'admin' Role

- Go to Roles
  - Add new Role `admin` with Description `${role_admin}`.
  - Add this Role into compositive role named `default-roles-{realm}` - `{realm}` should be replaced with whatever realm you created from `prerequisites` section. This role is automatically trusted in the 'Service Accounts' tab.

- Check that `account` client_id has the role 'admin' assigned in the "Service Account Roles" tab.
